Tennis: Kamke topples Del Potro at rainy Miami

Fifth-seeded Juan Martin del Potro of Argentina crashed out of the Miami ATP Masters on Friday, falling 7-6 (7/5), 6-1 to 89th-ranked German Tobias Kamke in a second-round match disrupted by rain.

Del Potro had just dropped the first-set tiebreaker when the match was halted by rain, the break lasting almost three hours.

The delay clearly did no favors to the world No. 7 from Argentina, who had stormed to the final of the Indian Wells Masters last week with wins over world No. 3 Andy Murray and world No. 1 Novak Djokovic.

His semi-final win over Djokovic in the California desert had ended the Serbian star's match winning streak at 22, but del Potro then fell to Rafael Nadal in the final.
